LUG-SOCKET FISHING TOOL.

T 0 all 207mm it may concern:

Be it known that I, THOMAS A. STEPHENS, a citizen of the United States, residing at larkersburg, in the county 01 \Vood and State of lV est Virginia, have invented certain new and useful Improvements in a Lug-fi ocket Fishing Tool, of which the following a specification.

This invention relates to fishing implements for removing broken drill rods, pump rods and the like from deep wells, such as oil wells, artesian wells, gas wells, and has for one of its objects to improve the construction and produce a device of this char actor of increased utility and simplicity.

lVith this and other objects in view the invention consists in certain novel features of construction as hereinafter shown and de scribed and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention;

Figure 1 is a side elevation, partly in secion of the improved implement.

Fig. 2 is a detached perspective view of one of the gripping elements.

Fig. 3 is a transverse section on the line 3-3 of Fig. l.

The improved implement comprises a stock or body represented as a whole atlO, and having means such as a tapered threaded stud 11 at one end, to enable the stock to be coupled in the ordinary manner to a pull element, not shown.

The stock 10 is formed with a downwardly opening longitudinally directed bore or socket 12 flaring at its open end as shown at 13, to enable the broken endof the rod to be fished to readily pass into the'socket. Formed through the stock are one or more elongated lateral openings 14.

Formed in the walls of the openings and extending into the body of the stock below the openings, are tapered guideways 15, each guideway having a stop shoulder 16 at its lower end, and opening outwardly at their upper ends in the upper ends of the openings as shown at 17.

Slidably disposed in each guide way is a correspondingly tapered gripping element 18 each formed with saw tooth shaped transverse members 19, the latter directed toward the interior of the socket.

By this arrangement, it will be obvious bers. By thi Application filed June 22, 1921. Serial No. 479,633.

removed from the well, the stronger the pull the more rigid the grip.

Extending transversely of each of the guldeways 15, is a supporting rod 20, and attached to each of the gripping members is an eye 21,

The eyes will be so located relative to the rods 20, that when the members 18 are in their upper or inoperative position, the eyes Wlll be disposed alongside of the rods to enable breakable elements, such as wooden rods 22, to be passed through the eyes above the supporting rods 20, as shown in Figs. 1 and 3, to temporarily support the gripping mem- 's arrangement when the stock 10 is lowered into the well to engage over the broken end of adrill or pump rod, the gripping members will not interfere with the entrance of the broken end into thesocket, but when the broken end of the rod engages the suspending members 22, the latter Wlll be broken and release the gripping members 18 which at once move downwardly by gravity and engage the rod. Thereafter an upward movement of the pulling element will cause the gripping members to firmly engage the broken rod and enable the latter to be withdrawn.

The improved device is simple in construction, and can be inexpensively manufactured, of any suitable material and operates effectually for the purposes described.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

What is claimed is 1. An implement of the class described comprising a stock adapted to be attached to a pull member andhaving a longitudinally directed socket with transverse openings communicating with the sockets and tapered guideways communicating with the openings and with the socket, and tapered gripping members slidable in the guideweys and inserta-ble into the guide-Ways through the openings.

2. An implement of the class described comprising a stock adapted to be -attached to a pull member and having a, longitudinally directed socket With tapered guideweys communicating with the socket, tapered grip ping members slidable in the guidmvays.

supporting rods transversely oi" the socket, l0

and breakable elements coupled to said gripping members and supported by said rods.

In testimony whereof, I affix my signature hereto,

THOMAS A. STEPHENS.
